WILLIAM A. TURNER, OF PROVIDENCE, RHODE ISLAND, ASSIGNOR TO THE RETORTGAS STOVE COMPANY, OF SAME PLACE.

GAS-STOVE.

SPECIFICATION forming part of Letters Patent No. 245,416, dated August9, 1881.

Application filed February 5, 1881.

To all whom it may concern:

Be it known that I, \VILLIAM A. TURNER, of the city and county ofProvidence, and State of Rhode Island, have invented a new and usefulImprovement in Gas-Stoves; and I hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawings, forming part of this specification.

This invention has reference to an improvement in the construction ofgas-burners for gas-stoves; and it consists in the peculiar constructionof the burner, as will be more fully set forth hereinafter.

To construct a durable burner for a gasstove a cast-metal head and plateare required, between which the orifices for burning the gas arelocated, so that the gas will burn around the closed head, and the heatacquired by the head will be partly utilized to heat the gas before itis burned.

In such gas-burners as heretofore constructed, the top was secured tothe lower plate by means of wrought-iron bolts, and usually per- .2 5forat-ed plates or perforated sheet-metal gauze was thus secured betweenthe head and plate, or, as it may be termed,between the upper and lowerpart of the burner. Such bolts areliable to get loose by reason of theconstant expan- 3o sion and contraction of the cast metal and theWrought-iron bolts, caused by the high heat to which they are exposedwhen the burneris in use and the low temperature when notin use.

To avoid this difficulty and cheapen the 5 manufacture of gas-burnersfor stoves is the main object of this invention.

Figure l is a sectional view of a gas-stove provided with my improvedburner, which is shown in elevation. Fig. 2 is a sectional view of theburner. Fig. 3 is a view, partlyin section, of what is usually called anursery burner.

Similar letters of reference indicate corre sponding parts.

gas. Shoulders are formed on the head a and lower part, I), of theburner, against which a screen of wiregauze or perforated sheet metal isseated to inclose the space between the head and lower part of theburner, and divide the gas issuing from such. inclosed space or chamher0 into a large number of line jets.

(Z d are two or more stays extending from the lower to the upper part ofthe burner.

The head a, the lower part, b, and the stays are all cast in' one piece,and the burner so made is not liable to the varying expansion, as thewhole is cast in one piece of one kind of metal, no bolts, nuts, orother loose part being used.

The burner-head is molded from a pattern having suitable core-prints,and a coreis then set into the mold, so as to fill up all the interiorspace, excepting where the stays d are required. After casting the coreis removed and the burner is ready to be tapped to receive the gas-tubee,- and if a wide annular opening is made, a band of perforated sheetmetal, f, is secured over the same, making a substantial, cheap, anddurable gas-burner for gasstoves. The large interior space forms aheating and mixing chamber for the gas and air before they are burned onthe outside of the The gas is supplied from the opening g and the airenters by the openin gs h h.

Having thus described my invention, I claim as new and desire to secureby Letters Patent The combination, substantially as before set forth, ofthe burner composed of a circular base-plate and a solid head supportedthereon by stays, all cast in one piece, and the screen drawn aroundshoulders formed respectively on the base-plate and head, and having itsends suitably united, so as to encircle the space between the base-plateand head, to form therewith a gas and air mixing chamber.
